(n.) A joke so poorly told and unfunny that you can’t help but laugh. Lame; a lame joke.

Today’s obscurity is a slang word from Indonesia, and a tough one to prove, as one man’s junk is another man’s treasure, so to speak – everyone has a different sense of humour, and what is funny to one person may be lame to another, and visa versa. But there have been enough bad jokes and opinions over the years that someone came up with a term for them. In English, I’ve always known such jokes as “groaners”.

Here are a few examples:

I bought a ceiling fan the other day.
Complete waste of money. He just stands there applauding and saying “Ooh, I love how smooth it is.”
